Application filed March 26,1907. Serial No. 364,687-

To all whom it may concern:

Be it known that I, JOHN PIErtsoN, .Tr., a native citizen of the UnitedStates, residing at Attica, Kan

sas, have invented certain new and useful Improvements inWhiflletree-Hooks, of which the following is a specification.

My invention relates to improvements in whiflletree hooks.

The object of the invention is to'produce a strong, durable andefiicient construction which may be easily applied to the whiflletreeand which when in place will be free from all liability of becomingaccidentally detached.

With these and possibly other objects in view, the invention includesthe particular features of construction hereinafter described andparticularly pointed out in the appended claims.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of a whiflietree showing the hook attachingdevice in place, one end being in section. Fig. 2 is a transversesection. Fig. 3 is a plan view of a modified form, and Fig. 4 is atransverse section of the same.

Referring by reference characters to the drawing, the numeral 5designates the whiflletree which is of wood, and G the hook attachingdevice. This is made of sheet metal having the body curved into nearlycomplete cylindrical form and having side flanges 6 designed topenetrate the wood to hold the clip against endwise movement and havingparallel lips 7 provided with perforations for the reception of the bolt8 to draw the lips together to clamp the band around the whiflletree.The wood of the whiffletree is provided with annular grooves as shown onthe righthand side of Fig. 1 and in dotted lines in Fig. 2 into whichthe flanges G enter, whereby all danger of the slipping off of the bandis prevented.

In the modified iorm shown in Figs. 3 and 4 I provide the end of thewhiifle tree with an inclosing metallic sheathing 8 of interruptedcylindrical form which has an inwardly struck portion or annular head 8designed to rest in an annular groove in the whifiletree. A splitclamping ring 9 having its inner surface designed to fit in the inwardlystruck portion of the sheathing rests in the groove formed by suchinwardly struck portion and its ends being drawn together by the bolt 10the entire device is effectually held in position. The whiflletree hook11 is secured by the bolt 10.

Having thus described my invention, what I claim In combination, awhifiletree having an annular groove, a metallic sheathing on the end ofsaid whifiletree having an inwardly struck portion designed to rest inthe annular groove of the whillletree, a split clamping ring having anannular bead on its inner surface designed to fit into the inwardlystruck portion of the metallic sheathing and means for clamping the endsof said split clamping ring, substantially as described.

In testimony whereof, I aflix my signature in presence of two witnesses.

JOHN PIERSON, .TR.
